Application tiled February 27, 1888. Serial No. 265,461. (No model.)Patented in England January 5, 1887, No. 14.4.

T0 all whom t may concern:

Be it known that we, GEORGE AsHworJrH and ELIJAH AsHwoRTH, engineers,subjects of the Queen of Great Britain and Ireland, and residing atManchester, county ot' Lancaster, England, have invented certainImprovements in Doft'er-Comb Heads t'or Oarding-Engines, (for which wehave obtained a patent in Great Britain, No. 144, dated January 5,1837,) of which the-following is a specication.

Our invention relates to the mechanism whereby rapid vibrator-y movementis imparted to the doliing-combs et' carding-engines. The parts wherebythe said movement is directly obtained are ordinarily inclosed in ametal box. Owing to the high speed of movement et the parts which are infrictional contact, it is ot' great importance that the bearings andrubbing surfaces shall be well lubricated, and that the lubricant shouldbe prevented from escaping from the box and bearings. In the presentpractice oil-holes are provided whereby oil is introduced to thebearings; but we have found that these holes also give access for theentrance of grit and dirt into the bearings and into the' oil in the boxor inclosed space, the oil beingI therebyT rendered less et'iicient as alubricant and the wear of the parts being increased. An additionaldisadvantage ot the present arrangement is that the oil is apt to escapepast the bearings and tiud its way to the comb-shaft and comb. 'loremedy these defects we close the box,so that it shall be as air-tightas is practically possible, the ordinary oil-holes in the shell of thebox not being provided, and we provide means whereby a supply of oil orother suitable lubricant can be introduced into the box, and we soconstruct the box as that all intercepted exuding oil shall be carriedoutside of the box into a dripper.

Our invention will be best described with reference to th e accompanyingdrawings.

.Figure l is a vertical section of the combmotion mechanism, taken atthe lin e of section coinciding with the axial line of the combshai't,parts beingin elevation. Fig. 2 is a similar view at right angles toFig. l. Fig. 3 is a plan view of the box with the cover removed and therevolving drip-catcher represented in i the comb-shaft passes to theoutside ot' the box. roo

horizontal section. Fig. 4.-

a vertical crosssection of the drip-catcher. Fig. 5 is a detached viewof the fastening for the bandpulley, which is formed in one piece withthe drip-catcher.

In Figs. l, 2, and 3, a is the comb-motion box, which is formed as ahollow pedestal pro! vided with a cover, l), which secured to the box bymeans oi' four screws, c c c c. The box a contains a certain amount ofoil, which 6o is indicated by the shade-lines, the said oil beingintroduced into 'the box through a holevl in the cover b. 'llo closethis hole, and also to provide means for gaging the amount of oil in thebox, we introduce a plug, d, having a reduced extension, d', which dipsinto the oil in the box and affords a ready means of ascertaining thedepth. Instead of the gageplug, we may use a gage hole or cock in theside Vof the box. The oil is maintained in the 7o box at a suitablelevel, so that the vibrating arm e within the box shall dip into the oiland effect the lubrication of all of the bearings lby the splashing ofthe oil. The gage d is provided as a guide to maintain the oil at theproper level, as it is important that there should not be an excess ofoil in the box lest such excess should interfere with the rapidvibratory motion of the arm e. The arm e is actuated in the ordinarymanner from a short spin- 8o dle, f, driven by a pulley, g, on the endof the spindle. The neck f of the spindle f is made conical, and thesliding block z'in the arm e is also formed with inclinedbearing-surfaces, so that by ad just-ing the bu sh i, which is screwed 85 into the side of the box and jammed by the nut fi', the wear ot' theseparts can be taken up. By the splashing ot' the arm e the oil is thrownup to lubricate the bearings of the comb-shaft c. Owing to the rapidchurningI 9o act-ion el' the crank and arm, it would be next toAimpossible to prevent oil from exuding through the bearings of thecomb-shaft and also through the joint which the cover h makes with thebox. Ie therefore form an intercepting-channelj, i n the box and covers.This channel extends entirely around the cavity of the box, and opensinto a chamber, l, which is an enlargement of the opening through whichThis chamber intercepts any oi the oil which works through the bearingand prevents it t'roin passing to the outside of the box. The oilintercepted by the channel j also Hows into this chamber. Ashield-plate, zu, haltl ofi' which is attached to the boxu and the otherhall` to the lid Z), elosely eneireles the comb-shaft, (shownV in dottedlines,) and still. .further cheeks the egress 'of oil troin the box. Ifthe oil were returned direetly into the interior of the box, the oilwould ehurn up the passage into th e eha'nlber l and the ehan nelj, andwould escape and be wasted, and also such escaping oil would pass ontothe eoinb-shatt and dainage the sliver. lVe drain the chamber by meansof a passage, 7n, and a spout, n, into the dripeatehero, which is formedin one pieee with the band-pulley I /,and is lixed upon the spindle f soas to revolve with it. It" preferred, the d rip-atelier and the pulley`may be sepzn'ate paris.

In the example the iin'issage m is bored in the metal of the walls ofthe box, and it will and diverts it into the pipe s, through whieh.

the oil Hows into a. assage,s", and passes into the box. It foundrequisite, a venthole may be bored in the lid b innnediat ely oppositethe arnl e. The pipe s is inade a niee tit in the bored passage s2, andis adjusted by turning the pipe within the passage. When adjusted, thepipeis fixed by ineaus oli' a screw, t. The drilreatcher is passml intoposition when 1 the mouth-piece s is turned into the position indicatedby the dotted lines in Fig. 4, the mouth piece bein g afterward turnedinto working position.

In Figs. l and 3 flats appear upon the pipe .sin order that it may beturned by means of a key. Then the drip-catcher is in position, a thinshield, u, is passed into position, and is seeure l to the turned boss(l. This shield just elears the revolving d rip-Catcher and cheeks theentry el dust and finti' into the drip-catcher and the bearin of thespindle j". The said shield also gives the apparatus a neater amiearaneeand boxes the parts in, lea-vil'ig only the pulley g exposed.. Thedripeateher, with its pulley g, is secured to the spindle by means of anut, I1'.

The boss ot the pulley or drip-eateher is made slightly taper, and isformed with a sere\\'-thread, and is also split, as shown at Fig. 5, sothat when the nut is tightened the spindle is lfirmly gripped.

In testimony whereof we have signed our naines to this speeitieation inthe presenee ot' two subsaibing witnesses.
